I just want to repost what nauticant said upthread:
Like others, I think the appeal with be successful and the decision of the lower court (the High Court) will be overturned. I think the basis for the overturning will be that the case was a judicial review and the lower court got drawn into thinking about right and wrong when they should have been considering whether the practice of the Tavistock was legal.
If I've guessed correctly, and I hope I haven't, there'll be huge celebrations by trans activists, Maugham will be intolerable, but after the party when they see where things stand, and when their demands for things to return to how they were end up being ignored, they'll realise that this wasn't about what a court decided but was about professionals being reminded of their responsibilities, in the context of growing public awareness, and exposure to sunlight. This genie won't be fitting back neatly into the bottle.
I agree with this assessment. We have long come to realise that our preference for judicial reviews (that seek to right a wrong for everyone, without seeking to penalise individuals) was probably misguided, even if we had some success with them.
This is the second judgement that clearly acknowledged harm may be done by these policies and that the right way to address these harms is to sue for damages.
This will, in the end, also lead to policies being changed, but it is a very different and in many ways much more difficult to endure for the individuals in question as they will then also be accused of doing it purely for personal, financial gain.
The Tavistock will not in my view go on to happily sail into the sunset. The High Court judgement was a shot across their bows, and the NICE review of puberty blockers and cross-sex hormones has holed them under the waterline.
The ship is sinking. Who goes down with it will now depend on the lawsuits to come, but what was uncovered thanks to Keira Bell and Mrs A cannot ever be hidden away again.
